The process for canola seeds typically consists of five steps: oil seed handling/elevator operations, preparation of soybeans for solvent extraction, solvent extraction and oil desolventizing, flake desolventizing, and oil refining.
Cleaning, Drying and Preparation of canola seeds/ canola oil
As a first step the canola seeds/ canola oil seeds is cleaned and dried. Foreign material, such as stones, glass and metal is taken out by sieving and magnets and i s disposed of outside the feed chain.
Drying is performed whilst avoiding contact with combustion gasses unless natural gas is used.
Some oil seeds, like soybeans and sunflower seeds, may be dehulled after cleaning. After dehulling, the meal has a lower crude fibre content, and hence a higher protein content. The soya hulls can also be used for feeding purposes, as such or in pelletized form.
crushing and heating -----------solvent extraction ------------Desolveting and toasting -------------drying cooling and storage (crude Oil)
After pre-pressiing, most crude oil pressed out, while there is some percentages still inside the raw material. To get all oil pressed out, we need to take solvent extracting method. There are many advantages in solvent extraction:
a). high oil pressing rate, oil residual is no more than 1% in cake,
b). convenient for big capacity production,
c). high automatic control,
d). closed production condition, low temperature press, clean working condition,
e). easy access to solvent.
Cooking Oil Machinery Equipment Manufacturer: oil refining plant
Two processes have been developed for refining edible oils and fats; the decision as to which process is to be used depends on the types and qualities of crude oil to be processed.
Chemical refining is the traditional method, where the free fatty acids of the crude oils are neutralized with caustic soda. The resultant sodium soaps are separated by means of separators. The neutral oils are subsequently bleached and deodorized. This method can be used for reliably refining virtually all crude oils, including oils of low quality, with the exception of castor oil.
The mecilla rapeseed oil which is discharged from expeller presses has various solid content levels depending on the oil seed type and the condition of the press. In order to remove particularly large solid particles, the oil is usually fed into a settling tank, which is also used simultaneously as a buffer tank. In some installations, a vibrating screen is used for precleaning, or the oil is taken directly from the press to the press oil clarification unit.
A smooth action pump is used for conveying the crude oil to a heat exchanger, which is used for heating the crude oil to the optimum process temperature. A quantity of hot water corresponding to the content of phosphatides in the crude oil is added to the oil and mixed intensively. A special dynamic mixer, which simultaneously conveys the oil directly to the separator, is used for this purpose. The hydratable phosphatides swell immediately due to the particularly intensive mixing of oil and water, and no additional reaction time is necessary.
This degumming method is suitable for pretreating palm oil, palm kernel oil, coconut and olive oil as well as animal fats with the aim of reducing bleaching earth consumption in the physical refining process. This considerably improves the economy of this method.
This method is suitable for neutralizing predegummed edible oils or oils which originally only have a low phosphatide content. The free fatty acids are saponified with caustic soda, and the sodium soap is separated.
Some vegetable oils, such as sunflower or corn oil, contain waxes (long-chained fatty alcohols or fatty acid esters), which crystallize at lower temperatures and result in turbidity in the oil. Wet winterization in combination with neutralization is suitable for removing these waxes.
Oils and fats are a mixture of different triacylglycerols. If these contain a higher amount of saturated fatty acids, the products tend to partly crystallize at ambient temperature. Fractionation is a process to split fats and oils into a liquid part, the olein, and a solid fraction, the stearing.
